Abstract Intraorbital arteriovenous fistulas (IOAVFs) are rare vascular abnormalities. We describe a case of an IOAVF featuring a direct shunt between the accessory meningeal artery and the superior ophthalmic artery. A 55-year-old woman presented with a 1-month history of visual impairment in her right eye, and magnetic resonance imaging (MRI) revealed optic neuritis-like findings. Steroid pulse therapy temporarily resolved visual impairment. However, 1 month later, she experienced decreased visual acuity, ocular conjunctival hyperemia, edema, and a pulsatile murmur. Contrast-enhanced MRI and digital subtraction angiography revealed compression optic neuropathy due to an IOAVF. Following successful treatment with transarterial embolization, her symptoms disappeared.

Abstract Evaluating vertebral bone mass and quality in the elderly poses challenges due to degenerative changes. This study aims to elucidate the usefulness of the trabecular bone score (TBS) by examining the relationship between bone mineral density (BMD), TBS, and Hounsfield unit (HU) values. A retrospective analysis of 599 vertebrae from 152 patients (mean age 69.0 years; range 44-89; 74 males and 78 females) undergoing dual-energy X-ray absorptiometry (DXA) and CT scans was conducted. Vertebrae were categorized into three grades based on the degree of degeneration. The TBS was calculated from DXA images, and the HU value was measured by placing a region of interest on an axial image of the vertebral mid-body. One-way analysis of variance and Pearson’s correlation tests were employed to investigate the relationship between BMD and TBS or HU values. While lumbar BMD significantly increased (p<0.01) with degenerative changes, TBS and HU values showed no significant differences. The correlations between lumbar BMD and TBS values, and between BMD and HU values, were stronger without degenerative changes than with degenerative changes. Significantly different HU values were observed between the right and left sides of severely degenerated vertebrae. Severe degenerative changes, particularly those associated with sclerosis, may impact HU values. TBS exhibits greater potential than HU values as a complementary tool.

Abstract We developed a machine learning model for predicting prostate cancer (PCa) grades using radiomic features of magnetic resonance imaging. 112 patients diagnosed with PCa based on prostate biopsy between January 2014 and December 2021 were evaluated. Logistic regression was used to construct two prediction models, one using radiomic features and prostate-specific antigen (PSA) values (Radiomics model) and the other Prostate Imaging-Reporting and Data System (PI-RADS) scores and PSA values (PI-RADS model), to differentiate high-grade (Gleason score [GS] ≥ 8) from intermediate or low-grade (GS < 8) PCa. Five imaging features were selected for the Radiomics model using the Gini coefficient. Model performance was evaluated using AUC, sensitivity, and specificity. The models were compared by leave-one-out cross-validation with Ridge regularization. Furthermore, the Radiomics model was evaluated using the holdout method and represented by a nomogram. The AUC of the Radiomics and PI-RADS models differed significantly (0.799, 95% CI: 0.712-0.869; and 0.710, 95% CI: 0.617-0.792, respectively). Using holdout method, the Radiomics model yielded AUC of 0.778 (95% CI: 0.552-0.925), sensitivity of 0.769, and specificity of 0.778. It outperformed the PI-RADS model and could be useful in predicting PCa grades, potentially aiding in determining appropriate treatment approaches in PCa patients.

Abstract Muscle loss negatively affects gastrectomy prognosis. However, muscle loss is recognized as a systemic change, and individual muscle function is often overlooked. We investigated changes in the muscle volume of individual muscles after gastrectomy to identify clues for prognostic factors and optimal rehabilitation programs. Patients who underwent R0 gastrectomy for Stage I gastric cancer at our hospital from 2015 to 2021 were retrospectively selected to minimize the effects of malignancy and chemotherapy. Trunk muscle volume was measured by computed tomography to analyze body composition changes. Statistical analysis was performed to identify risk factors related to body composition changes. We compared the preoperative and 6-month postoperative conditions of 59 patients after gastrectomy. There was no difference in the psoas major muscle, a conventional surrogate marker of sarcopenia. There were significant decreases in the erector spinae (p=0.01) and lateral abdominal (p=0.01) muscles, and a significant increase in the rectus abdominis muscle (p=0.02). No significant correlation was found between these muscle changes and nutritional status. Body composition imbalance may serve as a new indicator of the general condition of patients after gastrectomy. Rehabilitation to correct this imbalance may improve prognosis after gastrectomy.

Abstract Endothelial cell polarity is fundamental to the organization and function of blood vessels, influencing processes such as angiogenesis, vascular stability, and response to shear stress. This review elaborates on the molecular mechanisms that regulate endothelial cell polarity, focusing on key players like the PAR polarity complex and Rho family GTPases. These pathways coordinate the front–rear, apical–basal and planar polarity of endothelial cells, which are essential for the proper formation and maintenance of vascular structures. In health, endothelial polarity ensures not only the orderly development of blood vessels, with tip cells adopting distinct polarities during angiogenesis, but also ensures proper vascular integrity and function. In disease states, however, disruptions in polarity contribute to pathologies such as coronary artery disease, where altered planar polarity exacerbates atherosclerosis, and cancer, where disrupted polarity in tumor vasculature leads to abnormal vessel growth and function. Understanding cell polarity and its disruption is fundamental not only to comprehending how cells interact with their microenvironment and organize themselves into complex, organ-specific tissues but also to developing novel, targeted, and therapeutic strategies for a range of diseases, from cardiovascular disorders to malignancies, ultimately improving patient outcomes.

Abstract  Eleven crops were cultivated: maize, sunflower, soybean, groundnuts, sesame, kenaf, barley, wheat, rice, potato, and sweet potato. The crop growth rate (CGR) and specific dark-respiration rate (Rs) were measured, and growth efficiency GE =CGR/(CGR+R) (R, respiratory loss) was calculated. In each crop, whole-plant Rs reached a maximum in the earlier stages of growth, declined rapidly until the early reproductive growth, and remained almost constant during the ripening period. The Rs of leaves was higher than that of stems during the reproductive growth period, except for maize and potato. The Rs of storage organs was highest in the earlier stages, followed by a rapid decline to similar or lower values than those of leaves and stems during the ripening period. The GE in whole plant was higher than 60% in wheat, maize, barley, sunflower, rice, kenaf, sesame, but lower in soybean, sweet potato and groundnuts, and lowest in potato, which was affected by the higher respiratory loss. The GE in whole plant during the reproductive growth period was significantly lower, which we attributed to increased maintenance costs due to the increase of non-assimilative organs, and decrease in the dry weight of vegetative organs. A positive correlation was observed between the carbohydrate content of storage organs and GE, indicating that a crop with higher carbohydrate content in storage organs tended to have a higher GE. Crops with higher protein and crude fat content in storage organs tended to have lower GE. The GE over the growing season was low for kenaf, a fiber crop which contains high molecular weight compounds such as lignin and cellulose, and lower for sesame, groundnuts, and soybean, which contain high oil and protein and have high respiration costs for the synthesis of storage materials, suggesting that these higher respiration costs are related to lower dry matter production and hence lower yields.
